BOOT AND SHOE LACE GUIDE.

Specification of Letters ateut.

Application led August 21, 1909. Serial No. 514,000;

permit of securing the tubular lacing guides tol the article to befastened like the well known lacing hooks.

According to my invention the curved tube is provided with hollow shanksor attaching eyelets which protrude from the tube body and are bent toform a clamping flange. These hollow fastening projections consistof,one piece of sheet metal with the tube body and are formed of a metalstrip which is thereupon cut into pieces and the blanks obtained arefinally bent and rolled into curved tubular lacing guides.

In the drawings Figures l and 2 show a frontand plan view respectivelyof a tubular lace-guide provided with two hollow attaching Shanks. Fig.3 is a cent-ral cross section and Fig. et a bottom view of a guidehaving one central fastening eyelet. Fig. 5 shows a lace-guide theattaching shank of which is provided with a flange and Fig. 6 is a crosssection of the same fixed to a piece of material. Fig. 7 is a view ofthe guide tube from below with the hollow shank bent tofo-rm a clampingflange which is provided with several hollows for preventing rotation.Figs. 8 and 9 illustrate the way of manufacturing laceguides with hollowShanks.

The short piece of tube l is provided'with hollow shanks 2 or eyeletswhich project from the wall of the tube and which, if arranged' inpairs, prevent the tubular laceguide from turning. But one centraleyelet '3 (Figs. 3, 4C) will keep the guide in its proper posit-ion,because it acts as a pivot for the two armed lever which the tube formsand as the' tension of the lace is equal at both ends of the tube,I theguide body will always come into its proper position.

The vhollow shankA or eyelet may be provided with a neck flange 4E (Fig.which is formed by upsetting, and serveson the'one hand 5to receive thepressure of the die of the fastening apparatus, land relieve the rguidebody of this pressure, and on the other hand to secure the guide body tothe leather (Fig, 6) l Y If the lace-guide possesses one central eye-Patented Apr.

let, it is advisable to secure the guide body against turning by usingwith. the attaching apparatus a bottom die provided with several spikesor projections. These projections form in the bent clamping flange 5ofthe eyelet aI number of hollows or recesses 6 (Fig. 7) -which areseparate from one another and may extend into the neck flange 4. In thismanner projections are formed on the'inner side of the flange v5 whichenter the leather 7 or the like material and clamp it together so thatturning is prevented.

rllhe lace-guides are manufactured in such a manner that hollowprojections 8 are produced in a met-al strip Q at suitable distancesfrom one another by a pressing or drawing action, whereupon the blanksl() which have to be bent and rolled are stamped 'out from the strip.Finally the blanks are bent into a curved trough by means of a suitabledie and mandrel and the bent piece is rolled by means of two dies into acurved guide tube in which the longitudinal edges 1l, l2 ofithe blankmake joint 13 at the top or the side. A

Having now described my invention what I claim as new and ask to secureby Letters Patent is:

An improved lacing guide formed of a single plate of sheet metal shapedto form an elongated tubular guide body curved in the direction of itslength, said guide body having tubular fastening Shanks formed from apart of the metal of the body and projecting at right angles from theaxis of said body, the free margins of said body being disposed in Hushedge to ledge abutting ioo relation and being'arranged on that side ofALQIS FREIHERR v; GILLERN,
